Inadequate mineral intake can be silent at first because the body compensates via stores and renal conservation. Over time, however, health and performance may decline: lower energy and slower recovery, more frequent infections, brittle hair/nails, cramps, poorer sleep, reduced focus, and weakened bone health. Problems can appear faster during high-demand periods—adolescence, pregnancy, intense training, older age, or chronic disease. A major pitfall is attempting to “fix it with supplements” without confirming which mineral is low and at what dose. Low dietary variety (highly processed, low legumes/vegetables) increases risk. Sustainable correction relies on strengthening the dietary foundation; supplements, if needed, should be targeted and time-limited with monitoring.\n\nSource note: NIH ODS mineral fact sheets (deficiency development and symptoms).
